Strategies for EVALUATION
Why do designers
evaluate their work ?
Designers evaluate their work for a number of reasons.
1. To find out how successful their products are.
2. To find out if it is possible to improve their products.
Producers and designers attempt to improve their products continually in
order that they are the most successful products on the market.
Can you think of products that are continually improved?

Designers use the following methods to evaluate the
products they design and develop -
1. The response of the customer

3. Checking if the product reflects the main
design specification points.
